Patented Aug. 4, 1931 FFEC EMIL R. KLEMM, OF CHICAGO, ILLINOIS, ASSIGNO'R, BY MESNE ASSIGNMENTS, T0 EMIL R. KLEMM, JR., GF CHICAGO, ILLINOIS ENGINE GOVERNOR Appncation nea April 2o,

This invention pertains to the general class of governors and particularly to a governor adapted for use with a fluid engine.

An object of applicants invention is the production of a governor for a fluid engine whereby the fluid passing into the .engine is regulated to control the speed of said engine. A further object of applicants invention is the production of a governor of this character which is adjustable so that the maximum speed of the engine may be regulated. A further object of applicants invention is the production oi a device of this character wherein the controlling mechanism is operated by the moving iluid. A further object of applicants invention is the provision of an auxiliary valve to relieve the drop across the device under certain conditions. A further object of applicantis invention is the )roduction of a device .of this kind whic, is simple in construction, of a .Small number of parts, easy to manufacture, durable, reliable and highly satisfactory for its intended purpose. Many other objects I md advantages of the construction herein shown and described will be obvious to those skilled in the art from the 4disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

The embodiment of applicants invention as disclosed and .described in this specification is particularly adapted for use with an internallcombustion engine, however, it is understood that same is not limited to this use but may beadapted to govern the flow of any 'Huid for any purpose, Applicants device includes a disk having a plurality of apertures and a second movable disk relative to said rst mentioned. disk and also having a plurality of ,apertures which may be brought into and out of Valignment with the apertures in said llrst mentioned disk, The disks being movable laterally relative to each other the maximum speed is con.- trolled by bringing the apertures into and out of alignment, it being understood that at 1928. Serial No. 271,492.

the greatest sneed, the adjacent faces of the disks are either in contact or in close proximity to each other. An auxiliary valve is provided to relieve the drop in the pressure across the governor at certain speeds of the engine.

In the drawings, wherein like reference characters indicate like or corresponding parts:

i Fig. 1 is a top plan view ofthe device;

Fig. 2 is a sectional elevation of the saine showing the device connected t passages leading from the carburetor and to the vengine;

Fig. 3 is a section on line 3--3 of Fig. 1; and

Fig. 4 is a section on line 4-4 of Fig, 2.

Referring now to the drawings, at 1 is shown a governor which includes a casing 2 normally interposed between tubular member 3 leading from the carburetor and tubular member 4 leading to the engine. Any suitable means may be employed for attaching the tubular members 3 and 4 to the casing 2, flanges 5 and 6 being shown which are secured to the casing 2 by means of bolts 7. Extending across the passage 8 of casing 2 is a support 9 having an enlargement 10 at the middle thereof with a bore 11 which accommodates stem 12 attached to the movable disk 13. A resilient member 14 is positioned between the disk 13 and the enlargement and the movement of the disk 13 under the force of the spring 14 is limited by means ot a stop 15 comprising a burr threadedly engaging the stem 12 and engaging the enlargement 10. Casing 2 is shown4 shouldered at 16 which shoulder is engaged by the .disk 17, said disk being held in position by a sleeve 18 disposed between same and a `tace ot the casing 2. Sleeve 18 is secured in place by the flange 5 on the tubular member 3. The sleeve 18 is pref.- erably provided with oppositely disposed recessed projections 19. The recesses 2O of the projections 19 form guides for the projections 21 shown oppositely disposed on the movable disk 13. rFhe recesses l2O and projections 21 allow for movement of the disk 13 along a line coincident with the longituglo dinal axis of its stem 12 but prevent circumferential movement of the disk 13. Casing 2 has a hollow projection 22, the hollow portion 23 of which accommodates a projection 24 on the disk 17. Disk 17 is adjustable circumferentially by means of the screws 25 and 26 threadedly engaging opposite sides of the projection 22 and abutting opposite sides of the projection 24C on the disk 17 Disk 13 is provided with a recess 27 into which open a plurality of converging channels 28 which have openings spaced about the stem 12. Stem 12 is provided with a recess 29 which accommodates the stem of a valve 30 which is provided with a resilient member 31 whereby the head of the valve 30 normally engages a valve seat at the end of a tubular .member 32 positioned within the aperture 27. lVhen the pressure on the headof the valve 30 reaches a predetermined amount the resilient member 31 yields and permits the valve to be lifted from its seat, thereby opening the channels 2S to the passage of fluid through the recess 29. It is, of course, understood that there is an aperture 33 at the center of disk 17 through which stem 12 and spring 1a pass. The channels 28, therefore when the valve 31 is opened, establish communication between the carburetor side and the engine side of the governor.

r1`he operation ofl the device is as follows: lVhen the governor is incorporated in the manifold of a gasoline engine between the carburetor and the cylinders and when the apertures in the disk 17 and the disk 13 are in alignment, the normal maximum flow to the motor is reduced to a very small amount. During the operation of the device, the disk 13 is dragged toward the disk 17 by means of' the fluid passing through the apertures in said disk. The degree to which the spring 14 is compressed is dependent upon the speed or amount of flow of fluid. When the motor has reached its maximum speed, of course, disk 13 contacts disk 17 or is in very close proximity thereto. The amount of flow at the maximum speed is made adjustable by means of the screws 25 and 2G. These screws control the degree to which apertures in the disks 17 and 13 are in alignment. The maximum speed attainable by the engine is thus made adjustable over the very large range. t very low speeds of the engine the flow of the fluid through the device is not particularly affected by an adjustment of the disk 17. The effect of an adjustment of the disk 17 becomes more pronounced at speeds near to the maximum speed or when disk 13 is in close proximity to the disk 17. lVhen the motor is operating at maximum speed, should the load on the motor be increased such as to reduce the speed of same, thus demanding more power from the motor, valve 31 assists in reducing the drop across the governor such as to release disk 13 from disk 17 and permit a larger flow of fluid to the engine.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, 0r uses mentioned.
